What is the Latest USB4? - Something Need to Know
The USB interface is the most frequently used and the most common mainstream interface in our daily life. In early September last year, the USB Implementers Forum (USB-IF) officially released the latest USB4 specification, which also means the whole new generation of USB4 is coming soon, and the electronic products equipped with the USB4 specification are expected to enter the market as soon as the end of this year.
On the basis of USB 3.0, the transmission speed and interface configuration of USB4 have changed a lot. Let’s take a closer look at USB4 new features.
Main Benefits of USB 4
1.USB4 will utilize the USB-C port style. And USB4 uses dual-channel transmission, the previous connectors, such as USB Type-A or Micro-B, only support single-channel transmission, cannot support USB4.
2.The transmission speed of USB4 supports the fastest 40Gbps, the same speed as Thunderbolt 3. Also, USB4 will provide better resource allocation, if you are use USB4 port to transport both video and data at the same time, the port will allocate bandwidth accordingly. For example, if your monitor is using 10Gbps of bandwidth, you have 30Gbps left for the other connections, such as an external hard drive. The overall speed and performance of the USB 4 architecture can be dynamically shared.
3.USB4 supports up to 100W USB PD charging, compatibles with the charging power of most devices, and solves the problem of insufficient power supply caused by too many external devices connected at the same time.
Thus it can be seen that USB4 is the most versatile, smallest and fastest physical interface available. Besides, backward compatibility with USB 3.2 / USB 3.1 / USB 3.0 / USB 2.0 and Thunderbolt 3, it means that work well with your existing USB cables, but only operate at their maximum rated speeds.
RayCue is excited about USB4 and looking forward to producing various related cables, hubs and other peripherals to help users make the most of this new standard!
